Theeasing member 4ha's fastened thereto in 'any suitable Inanner threadedstuds-27 and 28, and when the partshand 4 are assembled together thestuds`27 and 28 extend through the casing member 3 and the said threadedends are engaged by. the thread 7 onlthel bearing buslr1 ings-6, l'whichbushings are lshown in the assembledposition in'Fig. 1 and more indetail in Figs. 4.- and12. .From the latter figure itr will be seen thatthe Weighted arms 11 and -12 are' pivoted on the inner ends' of thebushings 6.

The bore of member 2 is adapted tofit over theA smooth end of the driven member 20'` which thus becomes,as has" been stated, a seat for carrying the driving member 2. The o'ounterbore 36 of the^`m`ember 2 is to give clearance for the nut 22 asis shown in Fig. 2.v The operation of the larms l1 and 12V is controlledby sets of springs 13, 14 and 15 in a manner similar -to that de-`seri'bedqin my patent-hereinbefore referred to. The operationvofkthese' springs Will therefore be'onlyvbrieiy described herein.Referringto Fig. 7, it Will be seen that the flanges 8 carry two `pins16. These pins support ylinks 17 and 18,'the other ends of Which areconnected to the members 11 and 1.2,` by pins 19 and it Will be notedfrom this figurethatthepins 16 and19 are inthe same straight line withthe centerA of the bearing bushings 6; 4When the Weighted arms 11 and l24are in this position any .torque appliedto the driving member 2 cannot;move theyarms outward yyet the armspll and 12 are free to` mov'e on thepivotpins `are assembled the ed portions 7 `entire casing itselfv4 4 19and Will move very easily and `for some into successive operationl andcontrol the movement of the arms 11 and 12.

The action of the'. arm's" 25 and 26 is controlled bya set of springs 13', 14 vand 15 similar to those used on the a'ins' 11'and 12, the same being fastened by any` suitable means,"suchavsfsere'vvs34, to said arms.
